Legendary singer-actor Kishore Kumar has become a source of inspiration for director Anurag Basu recently, who has now chosen to make a "colorful and entertaining" biopic on Kishore Kumar with actor Ranbir Kapoor essaying the lead role. Having heard the lead's story, the recent grapevine suggests that Ranbir's real life lady love has also been roped in to play one of the four wives of Kishore, in this biopic. Reportedly, Basu had claimed of late that Katrina may be seen either in his next movie Silence or the one after being this Kishore Kumar biopic. However, sources reveal that Katrina is extremely keen to opt out of Ranbir-Priyanka starrer Silence ensuring that she gets to play the role of Madhubala, along with Ranbir in the biopic. Well, a real life couple, to be husband and wife in the movie, is definitely something to vouch for, right viewers?
